EGG CRATE.

Application led October 28, 1921.

To all 'who/m, t may concern:

Be it known that I, Nici-roms SANDoR, a citizen of the Republic of Hungary, residing at Dresden, Saxony, Germany, have invented certain new and useful lmprovements in Egg Crates; and I do hereby declare the following to be a full, clear, and eXact description of the same, reference being had to the accompanying drawings, forming part of this specification.

rlhis invention -relates to a packing for eggs orvsimilar articles, particularly that form of packing which utilizes cell forming partitions lying at right angles to one another and interlocking. In the usual form of packing each layer is formed of two series of partitions, the iioors'yof each tier being formed by a sheet of material the entire length and A.width of the container. The present invention contemplates the omission of the vsheet material separating the tiers, forming egg-supporting seats in each layer on which seats are supported the eggs of the tiers above.each seat in the tier below beingl located at the center ofthe tier above.

A particular object of the present invention is the `formation of the partition itself, each of these partitions being similar and being formed of a material forming a hollow rectangle in cross section so that each partition is double walled, this construction greatly increasing the elasticity of the walls and consequently reducing the breakage of eggs.

A further object of the present invention is the provisionof egg seats laterally extending on either `side of one of the narrower surfaces of the partition, each lateral eXtension being of such length as to overlie the corresponding narrow section of each parvtitionofthe coeoperating` series, that is, the

series lwhich lies at right angles to the series of parallel partitions :having egg-receiving seats. The egg-receiving seats are in consequence of this construction supported by each pair of co-operating partitions, the

broken by a jar or blow parallel to its longitudinal aXis and that by virtue of the double wall partition the eggs toward the middle of the container cannot be broken by a jar parallel to a lateral axis of the egg.

A further object of the present invention lies in the provision of partitions having equi-distant eggaeceiifing seats in which the distance from one end of the partition to the nearest seat is very materially in eX- cess of the distance from the other end to the nearest egg-receiving seat. The purpose of this is to permit the use of a single type of partition which by being reversed may form the staggered tier above. i

l/Vhile there are a great many advantages obtained by staggering the partition walls so that the junction of the tier below lies in the center of the cell in the tiers above, it may sometimes be preferred to have all of the eggs in the same vertical line as is at present the custom. This is taken care of in a modilication of the present invention by l having each alternate tier of relatively small seats being integral with one partition and resting upon the partition at right angles. In order to further increase the factor of safety the small resilient tongues extending from the` `co-operating partition underlie the elliptical egg-receiving seat and consequently add to its strength. It has been found in practice that with this double wall construction with its interlocking' egg-reoeiving seats that an egg is practically never size and serving merely to separate the eggholding tiers.

In the drawings are shown two embodiments of my invention.

Figure l is a plan view of a container fitted with partitions made in accordance with my invention in its preferred form.

Fig. 2 is a plan view of the blank for a section of a partition before it is bent into form. p

Fig. 3 is a perspective of a portion of a partition.

Fig. 4i is a vertical section through the container showing the eggs in position.

Fig. 5 is a side view of a single partition.

Fig. 6 is a top plan view of a joint formed by two partitions.

Fig. 7 is a section taken on line 7-7 of Fig. 5. Fig. 8 is a modilication utilizing alternate series of slight heigh merely separating the tiers, and not containing eggs.

As will be seen from Fig. l which illustrates a rectangular box or `container 10 the partition strips cross each other at right angles interlocking in the usual and customary way in this art. The walls of the partitions are, however, double, the partitions being made of paper, card board, or any other similar substance preferably cut from a single sheet. lt will be understood that while have shown the partition walls ing position.

in all of the views in the preferred forni with egg seats l do not wish to be limited to this form and contemplate as my invention the provision of hollow partitions having double side walls and staggered in adjacent tiers so that each junction in the tier below lies in the center in the rectangular cell in the tier above.

Referring particularly to Fig'. partitions are 'formed ol a single sheet oit material creased or scored as shown by the dotted lines and out as shown by the tull lines. The scores l5 and 16 torintlie margin of what is termed throughout the specilication and claims as the bottom wall 1T. although it is obvious that in each layer the bottoni wall of one series is the top wall ot the series at right anglesthereto. The term.y however, is very convenient and it is possible to describe the structure with Lgreater exactness by the use of this possible incorrect term. The adjacent semi-circular cuts 19 and 2O form the lateral extensions 2l ot the elliptical egg-receiving' seats i2 at the same time forming an arch 23 in each ot the side walls.

The scores 25 and QG form the margin of the socalled top wall 27 which is not unbroken as is the bottoni wall l?. but is severed by the cuts 2S Ytoi-ming' resilient tongues 29. The small segmental sections 30 are entirely removed b v the curved cuts 3l and the straight cuts 32 co-linear with the scores 25 and 26, thus forming arches 3T. The cuts 33 and 34 together with the score form flaps 3G and corresponding slots 4t2. By making the score 35 a cut the tlaps 36 may be entirely removed as are the segmental sections 30, this being; purely a matter of choice but l lfind it preferable to use the score 35 and to bend bac-k the flap 35 to form a slight additional strengthening; rib between the adjacent side walls 38 and 39, the latter being formed by gluing the inargin l0 to the margin 4l. the short edee of the flaps 36 serving as a limit and `guide in pasting.

In assembling, the partitions of one series are arranged parallel to each other and with the so-called bottom side down, the lateral extensions 2l affording ample surface to maintain the partitions in a stand- The partitions ot the co-operating1 series are now placed over the first series and are pressed. down upon them with the four tongues in Contact. rlhe tongues are resilient and readily `jive to permit passage ot the double walls so that the partitions ot one series lit within'the slots termed by the score 35 and cuts 33 and 34, the cut- 33 being mid-way between the top and. bottorn scores Q5 and 16. Upon being assembled the tongues 529. due to their inherent resilience, snap back into place underlying the eggmeceivingg seats 22 in each case and serving to support the same.

All the various layers may be assembled at one time and then it will only be necessary to reverse each alternate layer for the cells to be properly staggered to bring aseat in the center ot the cell above and below. lt will be noted that an arch is termed at each end ol' each junction and italso should be noted that the lateral extensions 2l on the seats are ot such overhang as to entend an appreciable distance beyond the inner end ot the tongue 29 so as to rest firmly upon the so-called top wall 27. lt will thus be seen that the egg-receiving seats QQ would be afforded support at either side even in the absence oit the tongue 29, the latter, however, do aid, are found convenient and require no eXtra cost.

In the modification shown in Fig. 8 the egg containing layers are exactly as described but each alternate tier all is composed ot crossed interlocking partitions 45 ot but slight height serving merely to support eggs above and below and permitting the storingot the eggs in vertical alineinent.

`What I claim is:

l. l cell-forming' partition adapted to cooperate with other exactly similar partitions to form a plurality oi cells each partition consisting oli a pair of parallel side wallsv with integral top and bottom walls. said bottom wall being unbroken throughout the length ot the partition.

2. A cell-forming partition consisting oit a pair of parallel side walls with integral top and bottom walls. said bottom wall being unbroken throughout the length of the partition. and having a plurality of equi spaced enlargements.
